Sheng jian bao – Houston?

I grew up in Shanghai and sheng jian mantou were my favorite dish. As popular as xiao long baos have gotten I’ve always wondered why these did not get as popular in America. My assumption is because they’re harder to make. Was wondering if there are frozen options or if there are authentic options in Houston, which has a large Chinese population but in my search none of them have the flavor the original Shanghai version. I’ve only found them be true to flavor in Los Angeles and Seattle.
